This book presents new research related to femtosecond laser ablation, coherent control, electronic and thermal processes, coloring, nanoscale heat transfer, and corneal refractive surgery. With laser-pulse durations of one quadrillionth of a second, femtosecond lasers are poised to change the way research is done in a variety of disciplines in science, engineering and medicine. The ability to remove material with minimal collateral damage may be the most striking feature that has not been matched by any other material processing technologies. With the processing power carried by each pulse en

Laser ablation refers to the phenomenon in which a low wavelength and short pulse (ns-fs) duration of laser beam irradiates the surface of a target to induce instant local vaporization of the target material generating a plasma plume consisting of photons, electrons, ions, atoms, molecules, clusters, and liquid or solid particles. This book covers various aspects of using laser ablation phenomenon for material processing including laser ablation applied for the deposition of thin films, for the synthesis of nanomaterials, and for the chemical compositional analysis and surface modification of materials. Through the 18 chapters written by experts from international scientific community, the reader will have access to the most recent research and development findings on laser ablation through original research studies and literature reviews.

Sebastian Uhlig presents the first experimental investigation of self-organized surface structures (LIPSS) generated by ablation from different (semiconductor and metallic) targets with an ultrafast white-light continuum (WLC) spreading in wavelength from 400-750 nm. The main goal is to study the possibility of LIPSS formation upon irradiation with an incoherent and polychromatic light source (e.g. the WLC) in order to discriminate between the two debated formation scenarios. The generation of a suitable WLC in terms of sufficient white-light pulse energy, broad spectral bandwidth, and low spatial coherence for the LIPSS generation, as well as the characterization of this WLC are additional important objectives of this work. Contents Introduction to Laser Induced Periodic Surface Structures (LIPSS) Introduction to White-Light Continuum Generation Characterization of White-Light Supercontinuum Self-Organized Pattern Formation with Ultrafast White-Light Target Groups Lecturers, researchers and students in the fields of Material Science, Microsystems, Engineering The Author Sebastian Uhlig studied physics at Brandenburg University of Technology Cottbus-Senftenberg and wrote his Master Thesis at the Chair of Experimental Physics II, under the supervision of Prof. Dr. Jürgen Reif. Currently, he is employed at the Fraunhofer Institute for Photonic Microsystems in Dresden, where he works on integrated sensors for a new class of electrostatic actuators.

Femtosecond lasers opened up new avenue in materials processing due to its unique features of ultrashort pulse width and extremely high peak intensity. One of the most important features of femtosecond laser processing is that strong absorption can be induced even by materials which are transparent to the femtosecond laser beam due to nonlinear multiphoton absorption. The multiphoton absorption allows us to perform not only surface but also three-dimensionally internal microfabrication of transparent materials such as glass. This capability makes it possible to directly fabricate three-dimensional microfludics, micromechanics, microelectronics, and microoptics embedded in the glass. Further, these microcomponents can be easily integrated in a single glass microchip by the simple procedure using the femtosecond laser. Thus, the femtosecond laser processing provides some advantages over conventional methods such as traditional semiconductor processing or soft lithography for fabrication of microfludic, optofludic, and lab-on-a-chip devices, and thereby many researches on this topic are currently being carried out. This book presents a comprehensive review on the state of the art and future prospects of femtosecond laser processing for fabrication of microfludics and optofludics including principle of femtosecond laser processing, detailed fabrication procedures of each microcomponent, and practical applications to biochemical analysis.

This book provides a comprehensive overview of the clinical use of irreversible electroporation (IRE) – better known by its commercial name, NanoKnife – which is one of the most exciting new needle-guided cancer treatments. The coverage includes the history of IRE, general technique, preclinical research, applications in clinical practice and early clinical results, and future perspectives. Contraindications, treatment planning, potential complications, follow-up imaging, and other practical aspects are fully discussed, with highlighting of useful tips and tricks. Through the delivery of short but highly intense electrical pulses, IRE results in tumor cell membrane permeabilization, causing cells to go into apoptosis. The minimally invasive nature of IRE, combined with the prospect of completely eradicating tumors while preserving delicate structures in the ablation zone, makes IRE the object of worldwide clinical research. This book will be of value for practitioners and trainees in interventional and diagnostic radiology, surgery, medical oncology, HPB and gastroenterology, urology, and radiation oncology.
